Hi I just bought Billet-Tech Alternators and they sell it with 2.8 pulley should I change it to 3.2 ?
The car making 530hp with on 6000rpm kn 2.4 and 3.4 whipple coming very soon
You must use a Billet Tech pulley as they aren't interchangeable with OE types. It all depends on your lower size. I use their largest (forget the exact size) with my 6 lb.
